If you like modernist literature (Woolf! Joyce! Proust!), you’ll love this digital archive developed at Yale. Not only does it list many modernist texts by year with links to their online versions, it also traces the movement of several key writers from 1914 to 1926 and has a pretty informative wiki.
For instance, here’s what was happening 100 years ago in modernist land: the first volume of Proust’s In Search of Lost Time finally came out, Kafka published The Judgment, George Bernard Shaw’s Pygmalion premiered in Vienna and then London, and Igor Stravinsky’s The Rite of Spring was performed in Paris in front of an outraged audience. Not a bad year all in all.
